Robert Plant has scrapped an upcoming Spanish tour due to scheduling conflicts.

The former Led Zeppelin singer was scheduled to perform there with his band The Sensational Space Shifters in July (14), but dates have been cancelled.

A message on Plant's website reads: "It's with regret (sic) to announce that due to scheduling conflicts, the Sensational Space Shifters have had to postpone their Spanish tour. Tickets can be refunded through local ticketing agents."

It is not exactly clear why Plant and his band won't be able to perform in Spain this summer (14).
